BLLAST - Boundary Layer Late Afternoon and Sunset Turbulence

A study of the late afternoon transition of the atmospheric boundary layer

Topic and objective :
This project brings together research scientists who work on this transitory part of the day, where all competitive forcings are weak, turbulence is decaying and the boundary layer is beginning to stratify, at the end of a convective day. This transition remains poorly understood, though it may have significant impacts on trace gas transport and scale interaction.
